i The schednle referrecI-t'o in Vthese Letters Patent and making pan: of the same.

I, HENRY O. HUNT, of Amboy, ini the 'conntyfof Lee and State of Illinois, have invented certain Im.` provements in Window-Fastenings".`

The nature of said improvements consists in constructing the ordinary spring bolt of Asuch a' form as to render it self-acting, and thereby avoid thenecessity for holding th-ebolt back while raising and lowering the window.

In the accompanying drawlng- Figui-e1 is'a perspective` View of my invention.

Figure 2 is a sectional viewof the .case C. l'

Figure 3 represents the bolt B, and spring 1', detached from the case C.

To enable those skilled in the art to which my in rention relates thevbett-er to understand andto'con-l struct the same, I will describe it more fully. C, in fig. 1, is a case, composed of any-suitable ma- ,t'erial,' and is constructed in two parts, as shown by the parts C and D in fig. 2. v

The said case O is provided with wings or lags, L,

which wings or lugs have perforations, s, for screws, vby means of 'which it (the fastening) is attached to the sash. A

a represents the exposed portio'n of the bolt B,

.which is shaped like au acorn, but maybe of 'an y 0rnamental design.- From the edge of the acorn-shell, there is a projection, x, which is as' wide as the diameter of theacorn-shell. When 'the window is to be raised, the project-ion xis turned upward, 'as shown in figs. 1 and 3, until the projection comes in contact with the sash, which stops it at the right point. \Vhen thewindow is to be lowered, the projection'a:

must be turned downward until it again strikes the sash, when the windowjwill slide down without touching .the bolt, and be s'elflfastened when down.

`c e represent catches, l(which may be vmade of various patterns,) which are fastened to the window-stop with or by means of screws, fand there may -be `as' many of them as is necessary for raising the window to different heights. As shown in iig. 1,th e `fasteny -the plate C, thus forming a cylindrical recess for 'the bolt B and its spring lr, and, when the plate C isfast'- cned t'o the sash, the plate D, and bolt B, with 'its spring r, are all firmly held in position, and, at lthe same time, the bolt B is allowed a free reciprocating and rotary motion.

' In g. 3, the bolt 'B is shown disconnected with the case C, giving 'a view of the coiled spring fr, the acorn e, projection a, and bevel f,'the projection :c being. turned upward. The bevel f is also on the upper side ofthe bolt B, and the window may no w be raised without holding the bolt back, as it (the bolt) will pass the catches e and c' of itself, and when the bolt B is reversed by turning the .projection :v downward, thus bringing the bevel f on the under side of the bolt, it will then re'pass the catches e and e', and the window will be self-locked when down, and will remain so until the bolt is again reversed.

Thisbolt may be used either asa center-bolt, to be driven through the sash, or asa surface-bolt, by chang ing the construction of the case according to the man ner of its use,

I do not claim the use of a spring bolt as awindow# fastening, for that has long been in common use; but What I do claim as my invention," is- The rotating beveled bolt B, furnished wit-h`the projection x, (or its equvalcnt,) the coil-spring l:gaandV combined with s uitable catches on the window-frame, all arranged as an d for the purpose described.
